SPECXFICATION forming part of Letters Patent No. l763,'79, dated. J une 28, 1904.

Application filed October 9, 1903.

To rif/ZZ whom, t may emmer/'ia'A Be it known that l, JOHNA. MCMNUS, a citizen of the'lUnited States, residing at Philadelphia, county of vPhiladelphia. and State of Pennsylvania, have invented a certain new and useful lmprovementin' Devices for Loading or Unloading Trains of Cars, of which the following is a specification.

My invention relates to a new and useful improvement in a device for loading and unloading a train of cars, and has for its object to provide means whereby a whole train of cars may be loaded from one given point without moving the train and unloaded in the same manuel'. i

With these ends in view this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.

ln order that those skilled in the art to which this invention appertains may understand how to make and use the same, the construction and operation will now be described in detail, referring to the accompanying drawings, forming a part of this specification,l in whicl1 Figure l is a side elevation of three cars,

' showiig my improvement applied thereto, a

portion being shown in section. Fig. 2 is a plan View of lfig. l. Fig. 3 is a side elevation of the rear end of the conveyer. Fig. e is a sectional View through one side of the conveyer.

My invention is adapted particularly to railroad construction-trains, and it is a welllznown fact that'in order to load an ordinary train of cars from one given point it is necessary to either move the train forward or bachward as each car is loaded and also to do the same in unloading. My invention overcomes this' disadvantage by providingn an endless belt or conveyer extending from one end of the train to the other, .which may be moved by suitable motor or motors for loading or unloading the train. I ln the drawings, A.A represents channel-bars extending. along each side of the cars, and in these channel-bars are journaled at each end rollers B, upon which rests theupper run of the endless belt or conveys-r C, '.ihe lower modifications could be serrano. 176,395. uit model.)

run of the belt is of course between the roll-u i or conveyer C isl driven at the forward end motors, (represented at D;) the motors would be steam and operated from the steam-pipe extending from the locomotive. It will thus 'be seen that by properly moving the belt or conveyer by any suitable but preferably C the entire train could be loaded from the rear end, and by reversing the movement of the belt the' train could be unloaded at the rear end. 1

l have shown this device in the drawings in its simplest and crudest form, and it could be made in any manner desired. The eonveyer could be composed of slats, as shown, or a link belt could be used composed of section buckets or platforms or made in any other manner desired, and it would not be necessary to provide rollers from which the conveyor extends, as it could rest so desired; but thev rollers 'would probably be preferable, as they siderable friction.

l have not gone. into details in the construction of this apparatus, as l wish-.to claim, broadly, the idea of providing an endless conveyer extending from one end of the train to the other. Therefore l do not wish t0 be limited to the exact construction here shown, as

made without departing from the spirit of my invention.

Having thus fully described my invention, what l claim as new and useful is- 1; Means for loading and unloading a train comprising a plurality of cars, consisting' of an endless belt or conveyer extending longitudinally of the train from one end to the other, and means for moving this belt lungi-l tudinally,

on a solid surface, if-

as and for` the purpose specified.

would do away with eon- 2. In a train loading and unloading device,
